ALBERT L. MELVIN, OF DETROET, MICHIGAN.

AIQ'CEOR-PGST.

Application filed. November To all whom it may concern Be it known that T, ALi-inn'r L. MnLviN, a citizen of the United States residing at Detroit, county of Wayne, State ot lrlichigan, have invented a certain new and useful Tinproveinent in Anchor-Posts, and declare the following to be a fulhclear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specincation.

This invention relates to anchor posts and its object is a cheap and eflicient form 0t post for use in supporting the framework of billboards and the like and adapted to be driven into the ground and secured or locked against removal therefrom by pressure or force to which such post is ordinarily sub jected in use. The post usually utilized in supporting the framework of a bill-board, windmill or the like is provided with a broad base requiring an excavation of the ground to set the post or to remove it there from. With the form of post herein dis closed, such excavation in the setting or removal of the post is dispensed with, the post being adapted to be driven into the groui'id and means is provided for lockin or securing the post against removal there'rroin after being driven. A further object of the in vention is a post of the character stated provided with alocking means adapted to be unlocked by operation of a locking bar that extends to the surface of the ground. A further object is a post adapted to be looked after being set in the ground and that prevented from being unlocked by the attachment ot the superstructure to the projecting end of the post. The device herein disclosed diiiers from the device disclosed in my co-pending application, Serial No; 63,381 in that toe driving point herein disclosed is pivotally attached to the anchor post provid ing a driving point therefor, while in the copending application the locking device is pivotally attached to a slidable bar. These objects and the several novel features of the invention are hereinafter more fully described and claimed and disclosed in the preferred form of the device shown in the accompanying drawings in which- Figure l is a perspective view of a bill- Specification or Letters Patent.

Figs. 5 and 6 are details of a driving head employed in driving the post into the round aiidlocking the same in position. 5

Similar characters refer to similar parts throughout the drawing and specification.

The post is preferably formed of an angleii'on body 1, the two legs of which are apertured at 2, 2, near the upper end to which the superstructure is to be secured, preferably by means of bolts. Gne leg of the body is longer than the other as may be understood from Fig. 3, the long leg being apertured to receive a bolt 3, the other leg being shorter forming a shoulder l. The locking member 5 of the post is also of angle-iron form having a 6 apertured to receive the bolt 3 as is indicated in Fig. 2, and between this leg 6 and the long leg of the body memher 1 is a tubular spacing member 7 on the bolt. The two legs of the dog or locking member are snarpened at the ends as indicated in F 2, and the leg 8 of the said member 5 is curved at the bottom and as shown particularly in Fig. 8, and is fiat or straight at the upper end to engage the shoulder 41 when the dog is turned in alinement with the body.

A locking bar 9 is provided having a slot 10 through which passes a bolt 11 secured to one of the legs of the body member. This bar 9 is pointed at the lower end, as shown particularly in Fig. 3, and when the parts are in extended relation as shown in Fig. l, the said bar may be moved downward behind the bolt 8 and the tubular spacing member 7 holding the dog in extended relation with the body member as shown. In this condition the anchonpost may be readily driven into the ground, the bar 9 preventing movement of the dog 5 on its pivot 8. After the post has been driven nearly its desired depth into the ground the bar 3 may be pulled upward relative to the post by an implement having a catch adapted to engage the aperture 12 in the upper end 01? the looking bar. With the locking bar withdrawn further driving of the post causes the dog or point 5 to turn on its pivot by reason of the curved formation of the leg 8 ol the dog. lVhen the post has been driven suiliciently to turn the dog practically at a right angle, the bar 9 is again driven which at this time passes back of the squared or flat end oi? the leg 8 of the dog as shown in Fig. 3, thus preventing the turning of the dog to alinement with the body member. the parts in this relatively angular position, any ordinary pressure or force may not withdraw the post from the ground.

The locking bar 9 is less in length than the body member 1, the upper end oi? said bar when in the locked position indicated in Fig. 3, being below the aperture 2 in the upper end of the body member. In securing the superstructure to the said upper end of the body member the bolts therefor, or he framework itself, it it be secured on the inside of the angle of the body member, prevents relative upper movement oi the bar on the post. It is thus impossible to unlock the dog or retainer 5 with the superstructure in place. On removal of the superstructure, the said bar may be readily pulled upward as before stated and the post then readily withdrawn 1 the dog 3 naturally draws into alinement with the post and passes out through the same opening in the earth.

A driving head 14: is preferably ei'nployed with this anchor post having an angle shaped recess in the lower endthereo'f fitting the upper end of the anchor-post and having shoulder 16 with which said end oi the post engages. By use of the driving head, the upper end oi the post does not become mutilitated in driving, and

thus be used many times and moved fromplace to place without involving the cost of excavating to secure the post. The driving head also has a hole 17 oractically oi the same size as the locking bar 9 through which a driving implement may be inserted to drive the loclriiigbar 9 to locking position. lhis head serves as a guide for the driving implement.

From the foregoing description it becomes evident that the device is of simple and inexpensive construction. that the same maybe readily driven into the ground and locked in position therein against removal by ordinary pressures or force applied to the post itself and further, that the device may be readily unlocked from the surface of the ground and. when so unlocked, may be readily withdrawn for subsequent use.

Having thus briefly described my invenlVith hold the same in alinement with the body.

during the driving operation, the body memher and point having abutting portions when held 1n ahnement, the locking bar being movable relative to the point to allow the same to turn on its pivot to an angle with the body by driving of the body and the bar being adapted to be inserted between the end 01''? the point and contiguous end of the body member when the point is turned to an angle preventing return of the point to alinement with the post.

2. An anchor post comprising a body member formed of an angle iron, one leg thereof being longer than the other, a dog formed of angle iron, one leg of which is-longer than the other, the long legs of the dog and body member being apertured, a bolt therein providing a pivotal connection for the two parts, the shorter legs of the two members being brought into endwise engagement when the dog is turned to alinement with the body member, said dog providing a driving point, and a locking bar slidably mounted on the body member adapted to pass between the said bolt and the abutting ends of the two short legs to hold the driving point in alinement with the body member, said locking bar being also adapted topass behind the short leg of the pivoted member when turned to an angle with the body member to prevent movement of the dog on its pivot'by force applied to withdraw the post from the ground.

3. An anchor post comprising a body member adapted for the attachment of a superstructure thereto at one end, a driving point pivotally attached to the opposite end, a locking bar slidably mounted relative'to the body member adapted to hold the driving point in alineinent with the body member, the dog and body member having abutting portions when. in aline-ment to relieve. the pivot of the drivin strain, said locking bar also providing means for holding the driving point at practically a right angle to the body member to secure the post in the ground, the attached superstructure preventing withdrawal of the locking bar to release the driving point substantially as de scribed. V i

l. An anchor post comprising a body member, a dog pivotally attaohed'thereto at the lower end thereof providing .a driving point, the dog being simi ar in cross section to the cross section to the body member and when in alinement providing an elongation between the end of the point and the body preventing the movement of the point on its pivot substantially as described.

In testimony whereof I sign this specificaof the body member, and a locking bar slidably mounted on the body member adapted to be moved to engagement With the longitudinal side of the point to hold the point and body in alinement or when the point is turned at an angle to the body to be inserted tion.
